[BUG] Reference files with @ isn't working

Environment

• Claude CLI version: 1.0.83
• Operating System: Windows 11
• Terminal: Git Bash for Windows and PowerShell 7

Bug Description

Per official docs Reference a single file, using @src/path/to/file.ts should work, but it doesn't. When I type @ the file picker drops down and doesn't include the src folder. Tested it in multiple terminals, in and out of IDEs, and even downgraded to version 1.0.81, but on luck.

Steps to Reproduce

1. start claude code
2. type @ and observe the file picker
3. verify that src isn't listed and won't autocomplete

Expected Behavior

src should appear in the file picker and tab completion should work all along the file path until I ultimately select the file.

Actual Behavior

Described above - src isn't even listed.
